LT1534/LT1534-1Ultralow Noise2A Switching Regulators U FEATURESâ– â– â– â– â– â– â– â– â– â– DESCRIPTIO The LT Â®1534/LT1534-1 are a new class of switching regulator designed to reduce conducted and radiated electromagnetic interference (EMI). Ultralow noise and EMI are achievedby providing user control of the output switch slew rates.Voltage and current slew rates can be independently programmed to optimize switcher harmonic content versusefficiency. The LT1534/LT1534-1 can reduce high frequencyharmonic power by as much as 40dB with only minor lossesin efficiency.The LT1534/LT1534-1 utilize a current mode architectureoptimized for low noise boost topologies. The ICs include a2A power switch along with all necessary oscillator, controland protection circuitry. Unique error amp circuitry canregulate both positive and negative voltages. The internaloscillator may be synchronized to an external clock for more ...
